no such issue with both the internal keyboard & touchpad on my dad's old Toshiba Satellite 2013 laptop & running Win11 Pro 24H2 and the Toshiba laptop does use a Synaptics touchpad driver (specific to Toshiba only - driver version 19.4.3.195, which is the latest one I can use on the Toshiba) - they both work fine, even when not attaching an external usb mouse
I’ve seen similar behavior on a few machines after updating to 24H2. In some cases, the keyboard only works again after re-login or reconnecting the device.
Today I had it randomly on a 2013 Medion Laptop after a reboot (E6234): (including UEFI and SSE4.2, no TPM, so I had to use the bypass method.) OS: Windows 11 26H1 Pro Attaching external mouse and keyboard to log off and log on again, fixed it. (until you run into it again) CPU: Pentium B960 (SandyBridge) GFX: Intel HD 2000 Chipset: HM70 Panther Point 4GB DDR3 RAM Synaptics TouchPad PS/2 Had a American Megatrends Inc. BIOS 503 from 2012 (now updated to 506 from 2013.) Updating from within Windows 11 26H1 it rebooted with a fancy crisis update.
Installed 25H2 to that Medion Akyoa (E6234) from 2012 some time ago. It ran just fine over the last months incl. installing regular updates. Yesterday evening I updated it to 26H2, switched it on and off some times, while working with it. By switching it on today, it lost the trackpad and the keyboard, had to attach an USB mouse to log off the user and log in again, which brought back the trackpad and keyboard. Google adviced some things: -Modify the Registry to Prevent the PS/2 Port from Sleeping -Disable USB Selective Suspend Best "idea" could be a Reset BAT File: (which could be used in autostart, instead of using an external USB mouse every time) @echo off echo Resetting Keyboard and Touchpad Drivers... net stop kbdclass /y net stop mouclass /y net start kbdclass net start mouclass echo Done!
